The Sky5® SKY58105-11 from Skyworks is a Mid-Band (MB) and High-Band (HB) Front-End Module that supports 3G/4G/5G mobile devices. It has separate 3G/4G/5G PA blocks operating in the mid-bands and high-bands, a silicon controller containing an MIPI® RFFE® interface, RF band switches, MB and HB antenna switches, bi-directional couplers, and integrated filters. This module has one auxiliary MB Tx output for external filters and one auxiliary HB Tx output for an external filter. For the uplink, the PA blocks support a very wide bandwidth 5G NR operations up to 60 MHz for n1 and up to 100 MHz for n41. The module has two ANT ports that provide flexibility to support multiple ANT configurations and ANT swap functions.
The SKY58105-11 is optimized to meet 5G-NR and LTE Advanced requirements which utilize Carrier Aggregation for higher data rates. The combined filtering, RF matching, and TRx switching internal to the FEM optimize performance for popular Downlink (DL) CA band combinations, all in a compact and low-cost solution. It contains necessary components between the antenna and RFIC transceiver and is optimized to provide superior Rx sensitivity and Tx efficiency.
The SKY58105-11 is available in a 62-pad, LGA SMT package that measures 8.60 x 6.50 x 0.65 mm and is suitable for use in multi-band 3G / 4G / 5G mobile devices, handsets, data cards, M2M, and LTE advanced carrier aggregation (CA) applications.
